I'm just not understanding where you come up with the 2,700 number, unless you're aware of the exact length of the track, down to the foot. If you're basing your calculations on "ride time," they're probably off, because ride time doesn't always equal cycle time, especially in the case of FJ where I strongly suspect there will be separate load and unload areas. In that event, the ride time figure you've heard would likely be the time a passenger is actually experiencing the ride, not the amount of time it takes for a ride vehicle to pass the same point on the track twice (cycle time)
